Took a break from gaming for ~1.5 years for studies. Built a £1,500 PC. Gamed for 1 month and I was bored to hell. After collecting the dust for 3 more months, the PC was sold for 65% the value. Damage = ~500 quid.
I did something similar recently except I spent £875 on the PC but managed to recover £790 of it by accepting an item in PX + cash and selling the item for more than the owner deemed it was worth.
I guess this is the opposite of what the thread is about so to join in;
I bought a Ford Focus for £4400, which turned out to be a nail with a whole host of problems the trader managed to hide from me. An opportunity came up to buy a much more fun car from a friend so I ended up buying this while I still had the focus, then taking £1000 less than Id paid barely 5 months earlier as I was eager to get out in the new car. Bearing in mind Id fixed a couple of problems on the Focus and spent money advertising it and getting it washed repeatedly when people came to view, I imagine I lost about £12-1300 over the ownership.
On a plus note I did learn a lot about buying/selling cars, what to look for, fixing them etc, so it turned out to be a valuable lesson
